Description
Picea pungens 'Super Blue' shrub 80-100 cm C7.5 | Blue spruce
A blue spruce shrub brings evergreen structure and cool colour to the garden throughout the year. This plant is Picea pungens 'Super Blue', also known as Blue spruce, and is supplied specifically in a shrub form. Unlike a generic blue spruce tree or another trained form, this presentation has a defined, upright, compact and conical shape. It creates a clear silhouette without losing the strong character associated with this conifer. The evergreen needles range from blue and blue-green to silvery blue, giving the plant a distinctive appearance in both summer and winter. It can reach approximately 3 metres in height when mature. No precise mature width is supplied, so it is best considered for a position where its conical outline can develop freely. The blue spruce shrub is hardy and low maintenance once established, making it a practical choice for ordinary UK garden conditions. Its firm shape works well as a structural evergreen in a specimen position, a border or a suitable container, provided that space and drainage are appropriate. The plant is part of the picea genus and offers lasting colour without relying on flowers.
Key features of Blue spruce (Picea pungens 'Super Blue')
- Evergreen colour: The blue, blue-green and silvery-blue needles remain present through the seasons. They add cool colour and clear structure to a UK garden, including during winter.
- Growth and form: This blue spruce shrub has an upright, compact and conical habit. The supplied shrub form gives it a defined presence that is distinct from a full-sized spruce tree or another trained form.
- Aspect and soil: Choose full sun to partial shade. A brighter position supports the best colour, while good air movement and reliable drainage are important. It prefers humus-rich, slightly moist soil that is acidic to neutral. The soil should remain open and should not stay waterlogged.
- Flowering: It is not grown for an ornamental flowering display. No flowering display is supplied in the product data, so its value comes mainly from its evergreen needles, colour and shape.
- Garden character: This is a hardy, low-maintenance conifer shrub for a well-drained position. In an exposed UK garden, consider a sheltered site rather than assuming strong wind resistance. It fits naturally within a collection of conifers.
Uses of the blue spruce shrub in the garden
- Specimen planting: Use the blue spruce shrub as a specimen where its compact conical silhouette can be seen clearly. Its strong outline and blue needle colour create a defined focal presence without depending on flowers.
- Borders and groups: In a border, it provides an evergreen point of structure and a cool colour contrast. It can also be used in group planting, where the shrub form helps create a consistent, clearly shaped display.
- Containers: This blue spruce shrub can be grown in a suitable container where the space and growing conditions allow adequate drainage. Avoid placing it where prolonged drought or waterlogging is expected, as it prefers slightly moist but well-drained soil.
- Hardiness: The plant is very hardy, with a supplied tolerance of approximately -40°C / -17.8°C and USDA zones 3–7. This offers useful resilience for UK gardens, although hardiness does not mean complete immunity from all weather damage.
- Plant combinations: Combine it with evergreen shrubs, conifers and suitable border plants that enjoy sun to partial shade, open well-drained soil and acidic to neutral conditions. Use contrasting foliage colour and texture to highlight the blue-green to silvery-blue needles.
The blue spruce shrub is a strong choice for adding evergreen structure and cool blue colour to a well-drained UK garden or suitable container.
